<p>We should indicate in the function help that strpos is regexp based. <o:p></o:p></p>

<p class="MsoNormal">Hi,<br>
<br>
strpos is based on regexp, a '.' matches any character.<br>
To let the engine treat a . as such you need to prefix it with a<br>
double-backslash.<br>
<br>
strpos(to_string("area"), '\\.')<br>
<br>
